Abstract Two electrochemical methods were introduced for detecting the Degree of Sensitization (DOS)of two kinds of high purity stainless steels .The surface morphology of the electrodes was studied by SEM after EPR and PPT tests. The results showed that high temperature heat treatment at 1 100 for an hour followed by air cool(AC) would result in sensitization ,but water quench(WQ) samples remained unsensitied. Compared with conventional EPR test ,the PPT method has such advantages that it can be conducted at a higher speed and with less destruction, thus it is a practicable technique for the detection of sensitization of ferritic stainless steels.

Abstract The anniversary variation of phytoplasmal distribytion and amount in mulberry plants were determined by polymerase chain reaction.It demonstrated that the phytoplasma was unevenly distributed in its host and there was a cyclic variation of its amount at the same part in a year. The content increases in stem during the growing season and gets to a top in July and is undetected in winter . The content increases in leaves and get to the top in August.however, the amount is lower and hardly vary in root in all a year. There are more content of auxin, cytokinins and gibberellic acids in the diseased plant than those in the healthy ones. The hormone levels in mulberry are related to the phytoplasmal amount.
